“…5,6 SnO 2 is a degenerate semiconductor when it is non-stoichiometric due to oxygen vacancies or tin interstitials. [7][8][9][10] Pure and doped SnO 2 thin films on glass substrates are extensively used as electrodes in thin film photovoltaic solar cells. 11 Tin oxide films doped with fluorine (SnO 2 :F) are of the most commonly used transparent conducting oxides, because of easy fabrication, low cost, stability, and adequate performance.…”

SnO 2 thin films are usually used as fore contacts in superstrate thin film solar cells such as thin film CdS/CdTe solar cells. Doping SnO 2 with fluorine improves its electrical properties and increases its optical bandgap energy besides improving other optical parameters. SnO 2 :F thin films of thickness around 200 nm were deposited on glass substrates by the spray pyrolysis method at a substrate temperature T s = 480°C. X-ray diffraction and scanning electron microscopy showed that the films are nanocrystalline. The transmittance of the films was measured at room temperature in the wavelength range 290-1100 nm, and used to calculate the reflectance, which was in turn used to deduce the optical parameters, such as the extinction coefficient, refractive index, real and imaginary parts of the dielectric constant, and energy loss. The relationships between these parameters and photon energy were investigated and compared with the results obtained by other authors.

“…The highest doping efficiency is found to be 6.65% for 3 at.% Pr doping ratio. Although these results suggest that Pr element is not a good electron donor like Sb and F elements, its efficiency is close to those of Nb, Nd and W elements [8,44,45]. Mobility value of undoped SnO 2 film slightly increases from 18.96 to 19.99 cm 2 V −1 s −1 with increasing Pr doping content.…”

“…In the literature, although there are some studies on Nd, V, V/F, Nb, Nb/F, Mo, Mo/F, W, W/F, Cr, F, Sb-doped SnO 2 thin films, it is still important to make studies about improving and controlling properties of SnO 2 which is one of the most important TCOs. For this reason, a comparison of improving percentage of electrical and optical properties with the literature [8,14,16,20,39,45,47,[54][55][56][57] is made in Table 4. According to Table 4, some elements gave rise to a serious improvement in only one property (electrical or optical), a part of them introduced an average increment in both properties.…”

In the present work, an investigation study on the crystal structure, surface morphology, electrical conductivity and optical transparency of spray-deposited Pr-doped SnO 2 was made as a function of Pr doping content. The Xray diffraction studies indicated that the films were grown at the (2 1 1) preferential orientation. The values of crystallite size and strain were determined using Williamson-Hall method and they varied between 71.47 and 208.76 nm, and 1.98 × 10 −3 -2.78 × 10 −3 . As seen from Scanning Electron Microscope micrographs, the films were composed of homogenous dispersed pyramidal-shaped grains. The n-type conductivity of films was confirmed with Hall Effect measurements, and the best electrical parameters were found for 3 at.% Pr doping level. The highest optical band gap and transmittance values were observed for undoped SnO 2 sample. The highest figure of merit (Φ), which is a significant parameter to interpret the usage efficiency of conductive and transparent materials in the optoelectronic and solar cell applications, was calculated to be 2.85 × 10 −5 Ω −1 for 1 at.% Pr doping content. As a result of this study, it may be concluded that Pr-doped SnO 2 films with above properties can be used as a transparent conductor in various optoelectronic applications.

“…The obtained results revealed that conductivity of the deposited films was dependent on structure of films and substrate temperature. The doping effect of neodymium (Nd) on the characteristics properties of tin oxide thin films was investigated [13]. The optical, electrical, crystallographic and morphological characterizations revealed that neodymium doping significantly influenced the properties of tin oxide thin films.…”

Abstract. The present research study deals with the preparation of tin oxide (SnO 2 ) nanostructures using thermal oxidation method. At first, Sn thin film was deposited on silicon (Si) substrate by thermal evaporation and then, thermal oxidation of the deposited Sn thin film was carried out at the growth temperature of 100 o C with growth time of 1 hour in tube furnace. The structural property of SnO 2 nanostructures was investigated by using FESEM and EDX. The FESEM results showed that Sn was successfully grown on Si substrate and the SnO 2 nanoparticles with diameters of 97.5nm to 142nm were recorded. It was observed that the particles were agglomerated to form the SnO 2 particles. The radiation of sunlight illumination was conducted for four consecutive sunny days and the results showed that the highest reading 189.9 W/m 2 was recorded at day two for the daytime temperature 38 o C. It was also noticed that the highest solar radiation percentage at day two was measured 18.9%.
